Set Up and Operation
Before plugging the unit in, always make sure that the power supply matches the product specification
voltage. Do not attempt to operate a 120V specification product on 230V power, or vice versa.
Connect the device to the main power supply. The device can be music-controlled by its built-in
microphone.
The Interlock plug/remote plug and safety keys are included in the box.
The interlock is the “included-in-the-box” successor for the optional remote interlock (51316)
They should be kept with the Galactic laser !!!
The following safety precautions should be followed:
-The interlock plug should be placed on the backside (17) of your Galactic laser.
-The keys should be put into the lock (18) of your Galactic laser.
Warning
If the plug is not connected, your laser will not function.
If the key is not set to ON, your laser will not function.
Exclusion of liability
Be aware that in some countries, there are additional regulations, regarding the use of laser devices.
Therefore, we strongly advise you to check your national laws with the authorities: We don’t take any
responsibility for eventual discrepancies, changes or adaptions regarding lawful use of laser devices.

Control Modes
There are 4 modes: • Autoshow 1 Autoshow 2
• Musicshow 1 + Musicshow 2
• Master/Slave
• DMX512
One Galactic (Autoshow 1+2)
1. Fasten the effect light onto firm trussing. Leave at least 0,5 meter on all sides for air circulation.
2. When the Galactic is not connected by a DMX-cable, it functions as a stand-alone device.
Please see page 14 for more information about the Autoshow effects.
One Galactic (Sound-controlled Musicshow 1+2)
1. Fasten the effect light onto firm trussing Leave at least 1 meter on all sides for air circulation.
2. Turn on the music. If the device is set to sound, then the Galactic will react to the beat of the music.
Please see page 14 for more information about the sound-control options.
Multiple Galactics (Master/Slave control)
1. Fasten the effect light onto firm trussing Leave at least 1 meter on all sides for air circulation.
2. Always use a safety cable (ordercode 70140 / 70141).
3. Use a 3-p XLR cable to connect the Galactic lasers.
The pins:
1. Earth
2. Signal -
3. Signal +
4. Link the units as shown in (Fig. 3), Connect a DMX signal cable from the first unit's DMX "out" socket to
the second unit's "in" socket. Repeat this process to link the second, third, and fourth units.
You can use the same functions on the master device as described on page 14 (Autoshow 1+2 or
Musicshow 1+2). This means on the master device you can set your desired operation Mode and all
slave devices will react the same as the master device.
Multiple Galactics (Master/Slave control)

Multiple Galactic (DMX Control)
1. Fasten the effect light onto firm trussing Leave at least 1 meter on all sides for air circulation.
2. Always use a safety cable (ordercode 70140 / 70141).
3. Use a 3-p XLR cable to connect the Galactic lasers.
4. Link the units as shown in (figure 4), Connect a DMX signal cable from the first unit's DMX "out" socket
to the second unit's "in" socket. Repeat this process to link the second, third, and fourth units.
5. Supply electric power: Plug the end of the mains power cord into proper electric power supply
sockets. Do so for all units and the controller.
Multiple Galactics Pro Set Up
Max. 30 Galactics
Fig. 4
Note : Link all DMX cables and set dip switches before connecting electric power
6. Do not supply power before the whole system is set up and connected properly. Design your show
according to your DMX controller functions. See page 13 for more about DMX programming.
Fixture Linking
You will need a serial data link to run light shows of one or more fixtures using a DMX-512 controller or to
run synchronized shows on two or more fixtures set to a master/slave operating mode. The combined
number of channels required by all the fixtures on a serial data link determines the number of fixtures the
data link can support.
Important: Fixtures on a serial data link must be daisy chained in one single line. To comply with the
EIA-485 standard no more than 30 devices should be connected on one data link.
Connecting more than 30 fixtures on one serial data link without the use of a DMX optically
isolated splitter may result in deterioration of the digital DMX signal.
Maximum recommended DMX data link distance: 100 meters
Maximum recommended number of Galactics on a DMX data link: 30 fixtures
Data Cabling
To link fixtures together you must obtain data cables. You can purchase DAP Audio certified DMX cables
directly from a dealer/distributor or construct your own cable. If you choose to create your own cable
please use data-grade cables that can carry a high quality signal and are less prone to electromagnetic
interference.
DAP Audio Certified DMX Data Cables
•DAP Audio Basic microphone cable for allround use. bal. XLR/M 3 p. > XLR/F 3 p.
Ordercode FL01150 (1,5m.), FL013 (3m.), FL016 (6m.), FL0110 (10m.), FL0115 (15m.), FL0120 (20m.).

Control Panel

A. LED Display D. Down Button
B. Func Button E. Enter Button
C. Up Button
Control Mode
The fixtures are individually addressed on a data-link and connected to the controller.
The fixtures respond to the DMX signal from the controller.
DMX Addressing
The control panel on the front side of the base allows you to assign the DMX fixture address, which is the
first channel from which the Galactic will respond to the controller.
Please note when you use the controller, the unit has max. 13 channels.
When using multiple Galactic’s, make sure you set the DMX addresses right.
Therefore, the DMX address of the first Galactic should be 1(001); the DMX address of the second
Galactic should be 1+13=14; the DMX address of the third Galactic should be 14+13=27, etc.
Please, be sure that you don’t have any overlapping channels in order to control each Galactic
correctly. If two or more Galactic’s are addressed similarly, they will work similarly.
For address settings, please refer to the instructions under ”Addressing’ (menu d001)
Controlling:
After having addressed all Galactic’s, you may now start operating these via your lighting controller.
Note: After switching on, the Galactic will automatically detect whether DMX 512 data is received or not.
The problem may be:
•The XLR cable from the controller is not connected with the input of the Galactic.
•The controller is switched off or defective, the cable or connector is detective, or the signal wires are
swapped in the input connector.
Note: It’s necessary to insert a XLR termination plug (with 120 Ohm) in the last fixture in order to ensure
proper transmission on the DMX data link.

ILDA Control Mode
This laser has an ILDA DB25 port, meaning it can be controlled by the PC.
There is an auto transform set in the unit’s inside to transform the ILDA and preprogrammed shows. When
connecting the 25 pin cable, the unit will be controlled by a PC. When you disconnect the unit, it will
return to its preprogrammed program control.
In theory, as long as the ILDA B25 connector is connected, a PC can control this laser unit. But in reality,
some software programs cannot control this unit, because pin 4 and 17 of the output card are not
connected. In fact this is an easy to solve problem. As long as you connect them, you can control this
unit.
